  • Patent number: 7509198
    Abstract: A control system for a machine operating at a worksite is disclosed. The control system has a controller configured to recognize a feature of the worksite from a topographic map of the worksite. The controller is further configured to determine at least one characteristic of the recognized feature, and determine a desired excavation entry point into a surface of the worksite based on the at least one characteristic.
    Type: Grant

    Date of Patent: March 24, 2009
    Assignee: Caterpillar Inc.

  • Publication number: 20070131438
    Abstract: A method of increasing efficiency and avoiding or reducing potential stall conditions is accomplished by configuring a ripper of a track type tractor responsive to a net force vector acting on the ripper. The net force vector is indicative of the various forces and pressures acting on the ripper, and the values indicative of these forces can be sensed. For instance, the force and value indicative of the force magnitude can be sensed by monitoring driveline torque, whereas the force vector angle can be derived from ripper tilt and lift actuator pressures. The ripper is configured responsive to the force vector magnitude and direction either via a control algorithm, or by inputs generated by an operator.

  • Publication number: 20060222772
    Abstract: The present disclosure provides a method for producing a coating. The method may include providing a substrate material and initiating a coating-deposition process to apply a coating material to the substrate material to produce a coating on the substrate material, wherein the coating includes a diamond-like carbon coating. The method may further include monitoring an intensity of hydrogen-alpha emission of a plasma produced during the coating-deposition process and adjusting at least one process variable of the coating-deposition process to facilitate production of the diamond-like carbon coating.
